Acinar cell carcinoma in a 63-year-old woman. (A) Axial T1-WI reveals a well-defined isointense lesion in the pancreatic body with a small hypointense center, representing a cystic portion. (B) T2-WI in the axial plane shows an exophytic growing lesion in the pancreatic body with an intermediate signal intensity compared to the surrounding normal pancreas and a hyperintense, cystic component. (C) Fat-suppressed T1-WI in the axial plane obtained early after intravenous administration of gadolinium-chelate exhibiting atypical contrast behavior of the lesion, showing moderate homogeneous contrast enhancement of the lesion except for the cystic portion. (D) Fat-suppressed T1-WI in the axial plane obtained later after intravenous administration of gadolinium-chelate reveals a decline in contrast enhancement of the lesion.
